Hallo,

I noticed that for some larger wikis, the geo_tags.sql.gz dump file does not include any geotags found in articles. Is it possible to determine why this is, and for which languages this is the case?

For example, the geotags dump file for Indonesian (a wiki with

400,000 articles) is only 7kb large, and all geotags in it are from

user pages, file uploads, or file templates; but not from articles: https://dumps.wikimedia.org/idwiki/20181020/

Yet it doesn't take much effort to find pages that are geotagged, such as this one (see the infobox): https://id.wikipedia.org/wiki/London

I realise that there are a number of alternative tagging conventions. Does idwiki possibly use a geotagging scheme that is not supported by some part of this ingestion/export process? Which other wikis may fall in this category?

I tried to find the script(s) that populate the geo_tags table from page content but so far had no luck, as I'm not sufficiently familiar with WP's software architecture; if someone can point me in the right direction I'd be happy to investigate myself.

Many thanks!
